Classpath Exception in OpenJDK and Subclassing

[Clemens Eisserer]

Hi Alex,

> However, I cannot find anywhere does the term "link" used in the exception cover also subclassing and interface implementation?
> In other words, is one allowed to implement, for example, the Callable<T> interface or extend the Thread class and copy and
> distribute the resulting executable under terms of ones choice (ofc, complying also with other requirements of the last paragraph of the openjdk license file)?

Unfortunatly I don't have an answer to this question, however at least
one commercial java runtime implementation is based on the assumption
this is possible.
I once asked Leaning Technologies, the company behind  the in-browser
JVM "CheerpJ", for the sources of their platform specific runtime
classes and they declined my request citing the linking exception.

Best regards, Clemens
